No. They are giving a new confirmation number. But I'm not sure whether the old and the new confirmation numbers are both valid. I have received an email,well I am still keeping my old confirmation number but I clicked the link and I was given a new number. What a big deal, you can check with both old and new numbers, anyway it is the same entrant.
I received the e-mail, too. But have the same Confirmation Number, as a lot of other people on the forum. This is very strange that you got a new number. Can you confirm what time you received the e-mail?
